Specification of Lettws Patent. Patgntgd Sap-t, 231, 1943309,Application filed February 6, 1905.

Serial No. 2 M354.

7 Riven, a citizen of the United States, anda resident of Jersey City,county of Hudson, and State of New Jersey, have invented certain new anduseful improvements in Gas- Gondensers, of which the following is aspecification.

The object of my improvements is to provide an apparatus for condensingor consuming smokaiumes, gases, vapors and the like, either for thepurpose of rendering them inocuous or for divers manufacturing purposes,as, for example, forming solutions of gases or vapors; my apparatusbeing characterized by the features that it is simple of construction,cheap to build, inexpensive to operate, and highly eilicient in action.

One'embodiment of my improvements is illustrated in the accompanyingdrawings, wherein Figure l is a longitudinal vertical sectio throughanapparatus provided with my improvements, some of the parts being shownin elevation; Fig. 2 a plan view of Fig, l,-

partly in section, and partly in elevation, and showing port-ions brokenaway; F 3 a section through 3-3 in Fig. 1, showing parts in. elevation;and Fig. 4-, a vertical section through l4c in Fig. 2.

Describing now my improvements as illustrated in the drawings; theapparatus shown comprises an inlet chamber 1. and an outlet chamber 2;the inlet chamber comniunicat ing at 3 wit-h a chimney, smelting furnaceor other source of smoke, fumes or gases; this being the chamber in theapparatus which first receives said gaseous products. The outlet chamberscparhted from the inlet chamber. by a partition el, and receives I 7put 111 motion, the smoke, fumes or other the gaseous products afterthey have been treated by passing through the apparatus hereinafter tobe described, intermediate said chambers. From this outlet chamber 11ynon-condensable gases are delivered through the pipe 5, either into theair or elsewhere as desired. The inlet and the outlet chanr bers areadapted to hold liquid, and coinmunicate with each other below theliquid level through openings 6 in the partition 4i. Adjustable closingmeans may be provided for these openings in the form of movable gates 7.The inlet and outlet tanks further a communicate with each other bymeans of the screw conveyors 8 and 9 and by the condnit 10 connectingsaid conveyors. The first the openings 6 in the partition.

conveyor 8 may be described as comprising a plurality oi helical ortortuous passages, l1. 12, 13 and 1+. coiled around shaft 15, androtatable therewith; said passages being open at both ends. the openingsat the front end of the conveyor forming months or scoops which, as theconveyor rotates scoop up or entrap liquid and gases, and delivermerged, and is connected with the first conveyer through the closed boxor conduit 10. This conveyer 9 may be either of the same construction asconveyor b, excepting that it will preferably be of smaller diameter andhave longer helical passages, or it may take the form shown of anArchimedean screw in which the screw is mounted on the shaft 16 androtates inside the stationary casing 21.

Any suitable means may be provided for rotating the respectiveconveyers. in this instance they are geared together so as to be bothdriven by the same pulley 17, an inter mediate gear 18 being providedbetween gears '19 and 20 on the shafts 16 and 15, re spectively, tocause the conveyors torotate in the same direction.

T he action of the apparatus is as f0llows :-'ihe inlet and the outletchambers having been filled with miter, or other liquid suitable for theparticular purpose, to about the level of the shaft if) of the upperconveyor, and the said. conveyors having been gaseous material will besucked into the inlet chamber .l, and, along with quantities of liquid,will be delivered by the first convcyer S into the conduit 10, which inturn will 'convcy the discharge downward into the mouth of the submergedconveyor 9, which by its rotation will deliver the combined liquid andgases into the outlet chamber 2, any uncondcnsed gases passing upwardand off through the pipe 5, and the 1 liquid circulating, as shown bythe arrows in Fig. 2, back into the inlet chamber through The liquid andgases in transit through the first conveyer are subjected to a more orless intimate commingling, which is perfected by their transit throughthe second conveyer, due not only to the greater length of the helicalpassages in said conveyer'but also to the fact that the action takesplace under pressure due to the weight of the superimposed liquid.

' The ultimate result. is that there is a most effective extraction ofthe ingredients of the smoke, fumes, gases or vapors either in the formof insoluble matter or in the form of a solution.

It should be stated that by regulating the v relative speeds of rotationof the res ective conveyers, and by adjusting the ow of liquid from theoutlet chamber back into the inlet chamber by the manipulation of thegates 7, the level of the liquid in said outlet tank may be controlled,and the degree of pressure due to the superimposed liquid upon thegasesin the submerged conveyer, can therefore be regulated.

Haying thus described my invention what I claim 1s:

1. In an apparatus of the class described, the combination of a tankcontaining liquid; a device having a helical passage with entrance andexit openings, and rotatably mounted in a wholly submerged position insaid tank; a conduit communicating with the entrance opening of saidhelical passage and leading above the surface of the liquid; and. meansadapted to feed liquids and gases through said conduit into said helicalpassage,

2. In an apparatus of the class described,

a conduit; a device having a helical passage rotatably mounted in saidconduit; means.

adapted to feed liquids and gases into said conduit upon said devicewith the helical passage; and a li uid holding chamber adapted toreceive t e liquid delivered by the device with the helical passage andreturn same to the action of the aforesaid means for feeding liquids andgases into the conduit upon the device with the helical passage.

3. In an apparatus of the class described,

the combination of a tank containing liquid;

a device provided with a helical passage having entrance and exitopenings and r0 tatably mounted in a wholly submerged position in saidtank; a conduit connecting with the entrance opening of said helicalpassage and leading above the surface of the liquid; and means fordelivering li uids and gases down said conduit into sai entrance openingof the helicalpassage, comprising a device provided with a helicalpassage and rotatably mounted in partially submerged position in'saidtank and communicating with said conduit.

4. In an apparatus of the class described,

the combination of an inlet chamber con- 'taining liquid and adapted toreceive the gases to be condensed; an outlet chamber likewise containingliquid; a communication between said chambers for the circulation ofthe, liquid; a screw conveyer r0- tatably mounted partially below theliquid level in the inlet chamber; a second screw conveyer rotatablymounted wholly below the li uid level in the outlet chamber; and a conuit delivering the discharge from the first conveyer into the second.

5. In an apparatus of the class described, the combination of a tankcontaining liquid; a partition in said tank dividing same above theliquid level into two chambers; a screw conveyer rotatably mounted andpartially submerged in one of the tank-chambers, and having its deliveryend projecting through an opening in the partition; a conduit leadingfrom the delivery end of said conveyer to the mouth of a secondconveyer; and said second conveyer rotatably mounted in Whollysubmerged. position in the other tank-chamber.
